1.0 INTRODUCTION

Introduction

1.1 The Portable Combustion Analyzer

The Portable Combustion Analyzer (PCA) (Figure 1-1) is a commercial grade, hand held, combustion efficiency analyzer that is designed for

continuous

furnaces, appliances, and boilers. The basic instrument is supplied with a probe, instruction manual, batteries, and carrying case.

Introduction

1.2 Displayed Data

The PCA directly measures, displays, and stores the following data:

• Room Temperature in °F or °C (Primary Air/Ambient Temperature)

• Flue Gas Oxygen Content in %

• Flue Gas Temperature in °F or °C

• Flue Gas Carbon Monoxide Content (H2 Compensated) in ppm

(For analyzers having a Carbon Monoxide sensor)

• Flue Gas Nitric Oxide content in ppm

(For analyzers having a Nitric Oxide sensor)

• Pressure/Draft in Millibars, Pascals, or Inches of Water Column

(For analyzers having a draft sensor)

• Differential Pressure in Millibars, Pascals, or Inches of Water Column

(For analyzers having a draft sensor)

The PCA will compute, display, and store the following data for any of the seven standard fuels:

• Combustion Effi c ien cy in %

• Excess Air in %

• Flue Gas Carbon Dioxide Content in %

• Flue Gas Carbon Monoxide Content referenced to Oxygen in ppm

(For analyzers having a Carbon Monoxide sensor)

• Flue Gas Nitric Oxide Content referenced to Oxygen in ppm

(For analyzers having a Nitric Oxide sensor)

The seven standard types of fuels that can be selected are:

• Natural Gas

• Oil #2

• Oil #4

• Oil #6

•

Kerosene

• Propane

• Coal

The PCA continuously monitors flue gas exhaust conditions and updates the above displayed values during a combustion test. If the analyzer is equipped with an optional pressure sensor, then draft measurements can be made simultaneously with the combustion test, or made separately.

The analyzer has the capability of storing data that was collected during a combustion test or draft meas urem ent . The s tor ed d ata ca n then at a later date be either viewed on the PCA’s display, printed using an optional printer, or downloaded to a computer.

4.2 Sampling Hole Location

The analyzer requires that a ½" diameter sampling hole be made in the furnace stack to accommoda te t he p robe stop o n t he P robe a nd Hose Assembly.

Locate the sampling hole downstream from the last heat exchanger, and upstream from any source of dilution, such as a draft diverter (Figure 4-1)

For residential and light-commercial combustion-equipment applications, the following recommendations are applicable:

• Oil Gun Burners

stream from the furnace breaching, and at least 6 in. (15 cm) upstream from the furnace side of the draft regulator.

• Gas Burners

at least 6 in. (15 cm) upstream from the furnace side of the draft diverter on gas-converted units. For gasdesigned equipment, the probe may be inserted down into the flue through the draft diverter or hood.

4-2

Important!

As the distance between the last heat exchanger

and sampling point increases, stack loss will falsely decrease due to heat loss by convection from the flue or stack.

Calibration

NOTE:

by your nearest Bacharach Servi ce Ce nter. Calibr at ion, however, can be performed in the field if your facility has the necessary equipment and qualified personnel to perform the procedures described in the sections that follow.

Important! To prevent the loss of data during calibration,

perform the following procedures usin g fresh batteries, or using an optional Power Supply (see Section 3.2).

Do not make calibration adjustments to the instrument without applying calibration span gas. Making adjustments without applying span gas could render the instrument inaccurate or unusable until re-calibration is performed correctly with span gas.

Bacharach recommends that the PCA be calibrated

5.1 Sensor Check

Important! Before turning on the analyzer or performing

any of the calibration procedures, ensure that the analyzer will be sampling fresh air, and that the probe is at room temperature.

When the analyzer is first turned on and allowed to cycle through its

second warmup period, and while sampling fresh air, the sensors are

60 checked (read) and calibrated (set) to the following ambient conditions:

•

Oxygen sensor is spanned to 20.9%

• Carbon Monoxide sensor (if install ed) is zeroed

• Nitric Oxide sensor (if installed) is zeroed

• Pressure sensor (if inst alled) is zer oed

If a sensor problem is detected by the analyzer’s microproce ssor during the warm-up cycle, an error message will be displayed at the b ottom of the LCD display. Refer to Section 7.2 for a listing of the error codes.

6.3 Cleaning the Probe

The Probe Tube and the Probe Body will become dirty under normal use (the water trap’s filter element should prevent soot from reaching the analyzer’s internal components). If the probe assembly is not kept clean, it could become clogged and restrict the flow of gas to the a nalyzer , resulting in incorrect readings and calculations.

NOTE:

An analyzer that is used to sample natural-gas furnaces normally requires less frequent cleaning than an analyzer used to sample oil or coal fired furnace s.

Equipment Required:

• Alcohol

• Aerosol can of Automotive Carburetor Cleaner

• Clean Rag

• Source of Compressed Air (optional) Procedure:

Remove the rubber tubing from the barbed fitting(s) on the probe handle (Figure 3-2).

Carburetor cleaner attacks plastic components. Take precautions not to spray cleaner onto the probe handle or analyzer .

Insert the plastic-spray tube of the carburetor cleaner into the barbed fitting(s) of the probe handle; then liberally spray carburetor cleaner through the probe.

After spraying, remove all the residual cleaner by repeatedly flushing the probe with alcohol.

CAUTION:

Wipe off the surfaces of the probe and tubing with a clean rag.

Allow the parts to dry completely. If available, blow compressed air through the probe to expedite the drying process.

Reassemble the parts of the probe assembly.
